HAND PROPELLED PADDLE BOAT Filed April 20, 1929 2 Sheets-Sheet 2Patented Dec. 31, 1929 UNITED STATES PATENT OFFICE JOHN HENRY RATHBONEAND HERBERT RA'IHBONE, or srnnrronn, ENGLAND HAND-PROIPIELLED PADDLEBOAT Application filed April 20, 1929, Serial No. 357,671, and in GreatBritain May 17, 1 28.

tically uncapsizable, which has absolute freedom in the construction ofany portion of parts liable to cause injury to the occupants, which willbe easier to operate, which will be more comfortable to the occupantsand which will allow each paddle to be operated by a separate person.

According to the invention the boat is constructed with a pointed noseor how, a square stern, a fiat bottom, floor boards, covering all orpart of the bottom and bearers, two sets one near the stern facing thebow of the boat andthe other near the bow facingthe stern of the boat,the stern seat bea back rest for such seat, and a separate crank andhandle for operating each paddle wheel.

The invention will be described with re'l' erence to the accompanyingdrawings Fig. 1 is aplan of the boat. Fig. 1 is a plan view of paddlebox.

Fig. 2 is a longitudinal section of the boat. Fig. 3 is a transversesection thereof. Fig. 4 is an enlarged perspective view of one of thepaddles.

The boat is constructed with pointed nose or bow A, a square stern B, aflat bottom C,

forward seat F.

carried by the transverse bearers c and with vertical or approximatelyvertical sides I) curved from the bow to the stern. A seat E carried onbrackets e affixed to the sides of the boat is arranged near the sternand is provided with a back rest E preferably affixed to the sides oftheboat. The seat E faces towards the bow of the boat. A second seatFcarried on brackets f afiixed to the sides of theboat is arranged nearthe bow of the boat and the front of the boat forward of the seat F iscovered in with boards G to form a forward deck, the edge 9 of whichalso serves as a back rest for the The bottom 0 of the boat is coveredby boards C whichalso cover the transverse bearers 0 and provide a clearspace between theseats E and F. The boards extend the whole distancebetween the seats E and F so that should any water get into the boat itwill not come into contact with the occupants.

The seats E and F are wide enough to be each occupied by two persons andas the sides D of the boat are vertical or approx imately vertical thereis as much room at the bottom as at the top, thus allowing sufficientspace for the le s of the occupants.

Two paddles T1 are arranged one at either side of the boat sufficientlynear to the seat E so that they can beactuated by the occu- Each paddlepant or occupants thereof. (see Fig. 4) is constructed with four bladesh mounted on a square spindle M.

The blades h are carried in pairs one at each end of a pair of flatmetalstrips bolted to the square spindle h. The strips/i. carrying one pairof blades are straight and the strips it? carrying the other pair ofblades are bent in the plane of the blades so that they will pass insidethe other pair of strips 72. at the centre. The blades h are formed offlat material bolted, riveted or otherwise affixed to the strips. i l

The spindle 7L projects into the boat through the side being circular incross section at this end and aycrank or handleI-I is attached to theend of the spindle inside the boat. A suitable Water-tight packing orgland is arranged around the spindle 71,

where it passes into the boat to prevent water entering the boat aroundthe spindle.

One form of water-tight packing is shown 5 in Fig? 5 and 6. It comprisesa circular plate afiixed to the outside of the boat and having acylindrical flange is provided with a screw thread on its outer surface,the shaft h passing through the centre of the plate,

and a second circular plate K afiixed to the insideof the boat andhaving a flange-k the inner diameter of which is the same as the outerdiameter of the flange is so that it can be screwed on to the latter. Aplug or nut k is screwed into the flange k to compress .thetresilientpacking material-K .between it y and the end of the flangek .to form atight packing around 'theshaft h The ends of i the plug 12 .and flange kadjacent to the m,pack1ug K are preferably chamfered as shown. TheplateslK and K arebolted to theside'of the-boatsby the bolts k Thewatertight packing shown in Figs. 7 and :8 comprises two rectangularplates 1K and with central cylindrical flanges k and k" of equaldiameter through which the shaft It passes. A resilient packingK isfilace d between the chamfered ends of the anges h" and hiand iscompressed by the bolts k which hold the plates k and k in iposition.

The .paddlesHare housed in paddle boxes L which are semi-circular inshape-and are scurried on boards or plate Z projecting outwards from thesides of the boat. These plates or boards-l are connected both at thefront and back =.to thesides of the boat by diagonally arranged bars orstays M arranged as shown in either Fig. 1 or Fig. 1 whichserve asbuffers to guard the paddles and addle boxes. A convex iron :band M maye arrangedalong-theiedge.ofthe board l-to reinforce it. 7
